Treatment of Nonvital and Vital Dens Evaginatus Teeth in Young Patient
A 8 year old Thai girl presented with toothache, a discharging sinus tract at the buccal attached gingiva of lower right second premolar. Clinical examination revealed a nonvilal open root apex with an anormally of fractured Dens evaginatus on occlusal surface. Dens evaginatus was also found on the occlusal surface of a vital lower left second premolar with open apex. This case report showed treatment of Dens evaginatus for a nonvital lower right second premolar and a vital lower left second premolar in young patient. Treatment of a nonvital tooth was done by Apexification using Vitapex paste followed by root canal treatment and restoration. Prophylactic treatment in vital tooth was performed by reducing the height of the tubercle and making shallow cavity for lining with Ionosit to stimulate secondary dentine deposition. The treatment of the lower right and left second premolars were completed in two years and follow up for five years after treatment. The treated teeth showed the complete healing of apical tissue and complete root formation. They can normally function like other normal teeth
